"Like its previous stage, Parasect is an insectoid creature. However, in this stage, the mushroom has completely overtaken the host's body. The insect has been drained of nutrients and is now under the control of the fully-grown tochukaso." From Bulbabedia.

Oh and also Parasect's Info in Pokemon FireRed:

"It scatters toxic spores from the mushroom cap. In China, the spores are used as herbal medicine."

You know, this pokemon sounds a lot like a reference to the cordyceps fungus. Most of the details sound the same. Uh, except cordyceps is just a little bit meaner. You should probably just look it up. Anyways, nice drawing. I had a parasect in my fireRed team, he was actually a decent pokemon. Not the best, but pretty useful.
